What Is a Reduced Port Ball Valve?
A reduced port ball valve, also known as a reduced bore ball valve, is a quarter-turn valve with an internal bore smaller than the pipeline inside diameter. Compared with a full port ball valve, the reduced port design offers a more compact body, lower weight and more economical manufacturing cost while still providing dependable shut-off performance.
As a professional reduced port ball valve manufacturer, ZONCIC provides reliable valves in carbon steel, stainless steel and alloy steel materials. Reduced port ball valves are widely used in industrial systems where full bore flow is not essential and a cost-effective valve solution is preferred.

Frequently Asked Questions
What is the difference between a reduced port ball valve and a full port ball valve?
A reduced port ball valve has an internal bore smaller than the pipeline diameter, which makes the valve body more compact and economical. A full port ball valve has a bore closer to the pipeline diameter, allowing lower pressure drop and higher flow capacity.
What is the advantage of a reduced port ball valve?
The main advantage is a more compact structure and lower cost. Reduced port ball valves are often selected when full bore flow is not required and a cost-effective shut-off solution is preferred.
What standards can your reduced port ball valves be manufactured to?
We can manufacture reduced port ball valves according to API, ASME, DIN, JIS and GOST standards depending on export market requirements and project specifications.
What materials are available for your reduced port ball valves?
We can supply reduced port ball valves in WCB, LCB, CF8, CF8M, stainless steel, carbon steel and special alloy materials according to media and service conditions.
